“Communicating health risks and scientific uncertainty”

It is claimed we live in a ‘post-truth’ society in which emotional responses dominate balanced consideration of evidence. This presents a strong challenge to those who value quantitative and scientific evidence: how can we communicate risks and unavoidable scientific uncertainty in a transparent and trustworthy way?

I shall talk about formats for communicating quantifiable health risks using ‘expected frequencies’, and demonstrate user-friendly interfaces for predictions of the potential benefits and harms of treatments for breast or prostate cancer. But can we communicate deeper uncertainty about facts, numbers, or scientific hypotheses without losing trust and credibility? Randomised experiments suggest this may be possible, but there is still a challenge to adequately communicate the limitations in the underlying data.
